  <description>Umbelliferone is an organic compound with the formula C9H6O3 and an average molecular weight of 162.14 g/mol. Umbelliferone belongs to the hydroxycoumarins, a subclass of coumarins and derivatives within the organic compounds. It is further classified within the superclass of phenylpropanoids and polyketides. Biologically, it serves as an antioxidant (PMC13294913).

The compound is found in or released from 22 recorded sources across multiple sectors. These include electrical and electronic equipment, such as batteries, capacitors, cell phones, printed circuit boards, and wires and cables, as well as four additional sources in that sector. In the food, food processing and cookware sector, it is associated with food contact materials, food packaging, and the preparation of malt, vinegar, and wine or sparkling wine. It is also found in lubricants within the energy, oil and gas sector, medical devices in the healthcare, pharmaceuticals and veterinary products sector, and synthetic textiles, carpets and rugs in the textiles, leather and furnishings sector. Additionally, it is present in drinking water and water supply, along with three more sectors. Recorded exposure routes for the compound include oral, inhalation, and touch.</description>
